Can anyone help me with this one ? I've raised a support ticket but fear I may run out of diskspace beforehand !
RHEVM is reporting "Critical, Low disk space" on /var/log for a hypervisor.
I would like to understand how to clear this down and stop the alerts.
I have seen knowledge base article (https://access.redhat.com/site/solutions/289583) but it is not relevant as we are already running the vdsm package with the supposed fix (vdsm-4.10.2-1.6.el6).
It tells me I only have 50M of space left on /var/log"
Moreover, I'm slightly confused because /var/log appears to be both a memory based (tmpfs) filesystem and also a logical volume. Which is it, or is it somehow both ? I'm probably misunderstanding something.
Either way, df -h on /var/log shows 1.8G used of 2.0G , but du -sh of /var/log show only 290M.
[root@rhphyp03a log]# df -h /var/log
Filesystem Size Used Avail Use% Mounted on
- 2.0G 1.8G 92M 96% /var/log
[root@rhphyp03a log]# pwd
[root@rhphyp03a log]# du -sh
[root@rhphyp03a log]# cat /proc/mounts | grep "/var/log"
